Re: [ANN] Leiningen 2.3.2 released

2013-08-21 Thread Sean Corfield 
I went back to my Windows 8 laptop and updated lein.bat to the version
on leiningen.org and then tested the up/down-grades and they worked
perfectly - great to see the latest Windows batch file working so
well!

Re: Two Way DOM binding in clojurescript

2013-08-21 Thread Kevin Lynagh 
I just posted a 3500 word blog post on this topic:

http://keminglabs.com/blog/cljs-app-designs/

which outlines the relative merits and tradeoffs of using explicit DOM 
references with callbacks vs. Angular's dirty-checking model and interop 
with the library from ClojureScript.

cheers,

Re: problem with edn

2013-08-21 Thread kawas 
In fact never user *print-dup* when using edn to read back data


*print-dup* will output type and meta information that will not play well 
with edn
  user=> (binding [*print-dup* true] (pr-str (sorted-map :z 5 :a 1)))
  "#=(clojure.lang.PersistentTreeMap/create {:a 1, :z 5})"

This "#=" with raise a RuntimeException because there is no dispatch on "=" 
in edn

Not using *print-dup* may lose some important information on data
  user=> (binding [*print-dup* false] (pr-str (sorted-map :z 5 :a 1)))
  "{:a 1, :z 5}"  ;; this is a plain hash map

Just take care of providing your own custom tags to be able to read data 
correctly
  ;; clumsy example
  user=> (binding [*print-dup* false] (str "#treemap " (pr-str (sorted-map 
:z 5 :a 1
  "#treemap {:a 1, :z 5}"

You can then read it back with your custom reader
  user=> (edn/read-string {:readers {'treemap #(merge (sorted-map) %)}}
 (binding [*print-dup* false] (str "#treemap " (pr-str 
(sorted-map :z 5 :a 1)
  {:a 1, :z 5}   ;; this is a sorted map


Seems like it should be possible to easily provide default printers and 
readers for custom tags & data...

Cheers

Re: [ANN] Leiningen 2.3.2 released

2013-08-21 Thread Sean Corfield 
As I told Phil on IRC, the problem turned out to be an old lein.bat...

To test the theory of the old lein.bat, I fired up two of my VMs:
* Windows XP running Leiningen 1.6.1.1(!)
* Windows 8 running Leiningen 2.0.0-preview10

On both of these, running lein upgrade produced a message that upgrade
was not supported and the .bat file should be edited to have the
desired version of Leiningen, then run lein self-install. Phil
confirmed in IRC that is NOT the correct process and the lein.bat
script should not be printing that message!

On both, I downloaded the latest lein.bat directly from
http://leiningen.org and replaced the current version.

On Windows XP, I opened a cmd window and navigated to the folder that
contains curl.exe (previously installed - I never added it to my path)
and ran lein self-install

On Windows 8, I opened a cmd window and ran lein self-install (wget
and curl are already on my path due to GOW - Gnu On Windows - being
installed)

In both cases, the Leiningen upgrade completed smoothly and I was
running Leiningen 2.3.2 afterward.

So the moral here is:

* don't edit lein.bat to change the version - instead download the
latest version from leiningen.org!

I'll be interested to see what lein upgrade does next time on Windows,
now that I'm running the latest .bat file. If it suggests editing the
file, I'll open an issue :)

Sean

Re: problem with edn

2013-08-21 Thread kawas 
Never had time to play with edn and custom readers but they are funny :)

Use *print-dup* if you need to... just know how to custom read it :

  user=> (edn/read-string {:readers {'user.Foo map->Foo}} "#user.Foo{:a 1 
:b 2 :c 3}")
  #user.Foo{:a 1, :b 2, :c 3}

"#user.Foo[1, 2, 3]")

Re: [ANN] optparse-clj: Functional GNU-style command line options parsing

Hello again,

optparse-clj 1.1.1 now supports ClojureScript and may be used from
Node.js command line scripts produced by the CLJS compiler's :nodejs
target.

[guns.cli/optparse "1.1.1"]

If you're writing Node.js scripts in CLJS and want to present users with
a conventional GNU command line interface (clumped short options `-abc`,
--long-options with or without `=`), give optparse-clj a try!

problem with edn

2013-08-21 Thread Jim - FooBar(); 

Hi everyone,

I am trying to serialise a record with edn. I think I am using all the 
good practices but I get a weird error...I am using these simple functions:


(defn data->string
"Writes the object b on a file f on disk as a string."
[b f]
(io!
(with-open [w (clojure.java.io/writer f)]
  (binding [*print-dup* true
*out* w]  (prn b)

(defn string->data
"Read the file f back on memory safely. Contents of f should be a 
clojure data-structure."

[f]
(io!
 (edn/read-string (slurp f

and I am getting this error:
*
**RuntimeException No dispatch macro for: = 
clojure.lang.Util.runtimeException (Util.java:219)*


Out of curiosity I tried something simpler like this:

Clondie24.games.chess=> (defrecord FOO [a b c])
Clondie24.games.chess.FOO
Clondie24.games.chess=> (ut/data->string (FOO. :a :b :C) "FOO")
nil
Clondie24.games.chess=> (ut/string->data "FOO")

RuntimeException No reader function for tag Clondie24.games.chess.FOO 
clojure.lang.EdnReader$TaggedReader.readTagged (EdnReader.java:739)



What I am I missing? any suggestions?

Jim

Re: [ANN] Leiningen 2.3.2 released

2013-08-21 Thread Sean Corfield 
I have a working Leiningen. I have wget and curl via GOW - Gnu On
Windows. I have HTTP_CLIENT set as a global environment variable to:
wget --no-check-certificate -O per Leiningen's instructions. I'll see
whether the upgrade process works when 2.3.3 is released. That will
determine whether the HTTP_CLIENT bug Phil mentioned was indeed fixed
in 2.3.2.

Good to know that your installer packages an appropriate ca file. If
my future upgrades don't go more smoothly, I'll switch to your
installer.

Not really.  But if you took your existing leiningen off the path, and ran
the installer it might get things up and running:
It bundles a wget with an appropriate ca file, downloads the latest stable
lein.bat, lets you select a JDK path from those available, and it ensures
that lein.bat is on the path.

TeX is viewed as a document markup language but it is turing
complete. Occasionally people get ambitious. Here is 
executable lisp in a Latex document:

ctan.org/pkg/lisp-on-tex

Perhaps some bright spot can do a Clojure-in-tex during the
next Google summer of code :-)

Re: [ANN] Leiningen 2.3.2 released

2013-08-21 Thread Sean Corfield 
It doesn't seem related to either of those. It seems to be an SSL
certificate issue, perhaps #1287? (which Phil closed saying "build it
from source instead"). I guess I'm surprised the JAR cannot simply be
downloaded via a browser - that would seem the easiest way for Windows
users to get Leiningen upgraded, in the absence of wget / curl.

Phil mentioned something (in IRC? in the last thread about SSL
problems?) about self-install not respecting HTTP_CLIENT early enough
in the process and that was fixed (post-2.1.3) but I can't find a
related issue for that.

If what I'm seeing is related to that latter problem, then this should
already be fixed and shouldn't be a problem with future upgrades - I
just wanted to try to get confirmation of that before opening a new
issue.

Re: NotSerializableException clojure.core.Vec

2013-08-21 Thread Jim - FooBar(); 

Ok found where the problem was...

In order to get unboxed ints I used (vector-of :int ...) which returns a 
clojure.core.Vec object. That object is not serializable (I looked at 
the source) and therefore I am getting this exception...Is there a 
reason why these objects are not serializable?

Hi all,

I've a rather strange problem...I know that all clojure collections 
implement Serializable but when I try to use standard Java 
serialization on a vector of records I get this exception:


/NotSerializableException clojure.core.Vec 
java.io.ObjectOutputStream.writeObject0 (ObjectOutputStream.java:1180)/


observe this:

"DELETE3") *;;SUCCESS*

nil
Clondie24.games.chess=> (class (get *2 :position))
clojure.core.Vec


it seems to me that the [:position [0 0]] slot in the record is 
causing the problems because it is a Vec and not a Vector...but then 
this is my defrecord definition:


(defrecord ChessPiece [ image ;;not really an image but a fn that 
fetches the image

   ^clojure.lang.PersistentVector position
rank ^long value direction]
 core/Piece
 ...
 ...   )

any ideas? should I not have type hinted the record?

thanks in advance for your time :)

Jim

Re: Entwined STM V1.0

2013-08-21 Thread Ivan Koblik 
I have done the benchmarks and optimized the implementation. On my PC with 
the new changes TransactionalMap is up to 5 times slower than 
ConcurrentHashMap. You can find the benchmarks here:

https://github.com/CERN-BE/Entwined-STM/blob/master/src/test/java/cern/entwined/demo/clojure_benchmarks.clj

Just require the namespace and run either (time (run-concurrent-map)) 
or (time (run-transactional-map)).

Please note while ConcurrentHashMap is faster in this test it does not give 
same guarantees as the TransactionalMap. For example in the benchmarks I 
created 1 thread per key that is being incremented if there was more than 1 
thread updating the same key than ConcurrentHashMap wouldn't be suitable 
any more.

I will release the improved new version 1.0.1 later this week.

That misses the point of having a generic threading macro.

That's ugly.
